PRE-ORDER PHASE
Please understand that there will be zero returns/refunds honored for pre-ordered kits due to impatience or indecisiveness. If you are unsure that you can wait for both the pre-order phase as well as the fabrication and shipping times, please do not purchase a kit until the pre-order phase is over and all pre-ordered kits have been completed.
Pre-Orders will be accepted throughout August-September and fabrication will begin mid September. Updates will be posted to the Hellfire Fabrication Instagram if there are any delays. Fabrication will begin with the first order placed and move down the list in the order that orders are received.
Due to unfortunate ongoing global situations, shipping and material costs may fluctuate.
Shipping to Hawaii and Alaska won't be quoted properly via the website. Please email hellfirefab@protonmail.com if you are shipping outside of the lower 48 and would like to place an order.
Estimated build time: 6-8 weeks
Expect build time delays depending on demand, holidays, and weekends.
All products are hand made to order which takes time.
Feel free to contact me via email if you have any questions regarding build time or shipping costs.
The Bastard Pipe V2- The ONLY Modular Catback Exhaust System
What's different from the V1?
New options. Better flow. Lighter weight.
The single exit 5in now features a slight upward angle at the tip for a more aggressive touch.
The dump allows for maximum weight and dollar savings while still qualifying as a catback system.
The quads, dual muffler, and dual 5in are now all interchangable at the tip/axle back without needing a completely new Y pipe to change up your look. Each individual component will be available for purchase after preorders are complete.

This system is 100% modular, eliminating the need of purchasing an ENTIRE NEW exhaust just to change the sound, look, and feel of your build. Each section of the Bastard Pipe can be swapped out for a different variant/section allowing you to completely change both the visual of your build AND customize the tone of your exhaust. Being modular also allows you to save hard earned money when replacing damaged sections of exhaust from scraping or accidents. The Bastard Pipe aims to make custom fabrication much more obtainable than ever before. This is the last catback you will ever need.
2015-2021 WRX AND STI
Utilizes vbands to reduce the need of gaskets, allow for an easier install, and breaks the trend of using slip fits for "quality" performance parts.
Swap a single exit section out for a quad tip variant (or any other variants) in a matter of minutes.
Designed to bolt up to OEM/most aftermarket J-pipes.
BEST used in junction with the Hellfire Fabrication J-Pipe.
May require a tune/retune.
Professionally TIG welded and back purged.
Made of 3" 304 Stainless.
Off road use only.
Professional installation recomended.
Does not include gasket or adapter for OEM j-pipe to catback flange mating section.
Some minor adjustments may need to be made post install to ensure perfect alignment. Some trimming of rear bumper exhaust exit area may also be required to fit the quad 4in OD tips depending on diffusers, prior damage to bumper, shorter hanger bushings, etc.
Axle back style and tip color options are availble in the drop down menus.
Price varies depending on selection.
Single Exit - 5in OD at tip
Dump - 3in OD at tip
Quads - 4in OD at each tip (not available in burnt tip)
Dual Muffler - 4in OD at each tip
Dual Exit (no muffler) - 5in OD at each tip
ALL variants will come with a resonator section for best sound results. Maintaining the resonator helps with cabin drone. This does not impact backfire or turbo whistle noises.
It is recomended that you replace the exhaust hanger bushing with a stiffer newer bushing for the dump variant Bastard Pipe. Failure to do so may result in shifting of exhaust during spirited driving or aggressive turns which may cause rattling/clunking sounds. Recommended exhaust bushing upgrade here -> HANGER BUSHING
If you need a replacement section, please email or DM me on Instagram to order.
Each individual component option will soon be added to the website making it easier for you to place an order for replacement sections if you choose to do so.
Warning: When installing vbands, ensure that the threaded portions are not sticking off lower than the bottom of exhaust. These have the potential to snag over bumps/pot holes and lead to damaged vbands. This is most important for those that run a very low ground clearance suspension setup. Those running stock or track suspension setups should not see an issue with vband clock angle. If you are looking for an exhaust system that allows for maximum ground clearance, see Hellfire Fabrication Side Exits for the perfect low setup.
